+
+A library of string validators and sanitizers.
+
+## Strings only
+
+**This library validates and sanitizes strings only.**
+
+If you're not sure if your input is a string, coerce it using `input + ''`.
+Passing anything other than a string is an error.
+
+## Installation and Usage
+
+### Server-side usage
+
+Install the library with `npm install validator`
+
+#### No ES6
+
+```javascript
+var validator = require('validator');
+
+validator.isEmail('foo@bar.com'); //=> true
+```
+
+#### ES6
+
+```javascript
+import validator from 'validator';
+```
+
+Or, import only a subset of the library:
+
+```javascript
+import isEmail from 'validator/lib/isEmail';
+```
+
+#### Tree-shakeable ES imports
+
+```javascript
+import isEmail from 'validator/es/lib/isEmail';
+```
+
+### Client-side usage
+
+The library can be loaded either as a standalone script, or through an [AMD][amd]-compatible loader
+
+```html
+<script type="text/javascript" src="validator.min.js"></script>
+<script type="text/javascript">
+  validator.isEmail('foo@bar.com'); //=> true
+</script>
+```
+
+The library can also be installed through [bower][bower]
+
+```bash
+$ bower install validator-js
+```

+## Sanitizers
+
+Here is a list of the sanitizers currently available.
+
+Sanitizer                              | Description
+-------------------------------------- | -------------------------------
+**blacklist(input, chars)**            | remove characters that appear in the blacklist. The characters are used in a RegExp and so you will need to escape some chars, e.g. `blacklist(input, '\\[\\]')`.
+**escape(input)**                      | replace `<`, `>`, `&`, `'`, `"` and `/` with HTML entities.
+**unescape(input)**                    | replaces HTML encoded entities with `<`, `>`, `&`, `'`, `"` and `/`.
+**ltrim(input [, chars])**             | trim characters from the left-side of the input.
+**normalizeEmail(email [, options])**  | canonicalizes an email address. (This doesn't validate that the input is an email, if you want to validate the email use isEmail beforehand)<br/><br/>`options` is an object with the following keys and default values:<br/><ul><li>*all_lowercase: true* - Transforms the local part (before the @ symbol) of all email addresses to lowercase. Please note that this may violate RFC 5321, which gives providers the possibility to treat the local part of email addresses in a case sensitive way (although in practice most - yet not all - providers don't). The domain part of the email address is always lowercased, as it's case insensitive per RFC 1035.</li><li>*gmail_lowercase: true* - GMail addresses are known to be case-insensitive, so this switch allows lowercasing them even when *all_lowercase* is set to false. Please note that when *all_lowercase* is true, GMail addresses are lowercased regardless of the value of this setting.</li><li>*gmail_remove_dots: true*: Removes dots from the local part of the email address, as GMail ignores them (e.g. "john.doe" and "johndoe" are considered equal).</li><li>*gmail_remove_subaddress: true*: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "foo+bar@gmail.com" becomes "foo@gmail.com").</li><li>*gmail_convert_googlemaildotcom: true*: Converts addresses with domain @googlemail.com to @gmail.com, as they're equivalent.</li><li>*outlookdotcom_lowercase: true* - Outlook.com addresses (including Windows Live and Hotmail) are known to be case-insensitive, so this switch allows lowercasing them even when *all_lowercase* is set to false. Please note that when *all_lowercase* is true, Outlook.com addresses are lowercased regardless of the value of this setting.</li><li>*outlookdotcom_remove_subaddress: true*: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "foo+bar@outlook.com" becomes "foo@outlook.com").</li><li>*yahoo_lowercase: true* - Yahoo Mail addresses are known to be case-insensitive, so this switch allows lowercasing them even when *all_lowercase* is set to false. Please note that when *all_lowercase* is true, Yahoo Mail addresses are lowercased regardless of the value of this setting.</li><li>*yahoo_remove_subaddress: true*: Normalizes addresses by removing "sub-addresses", which is the part following a "-" sign (e.g. "foo-bar@yahoo.com" becomes "foo@yahoo.com").</li><li>*icloud_lowercase: true* - iCloud addresses (including MobileMe) are known to be case-insensitive, so this switch allows lowercasing them even when *all_lowercase* is set to false. Please note that when *all_lowercase* is true, iCloud addresses are lowercased regardless of the value of this setting.</li><li>*icloud_remove_subaddress: true*: Normalizes addresses by removing "sub-addresses", which is the part following a "+" sign (e.g. "foo+bar@icloud.com" becomes "foo@icloud.com").</li></ul>
+**rtrim(input [, chars])**             | trim characters from the right-side of the input.
+**stripLow(input [, keep_new_lines])** | remove characters with a numerical value < 32 and 127, mostly control characters. If `keep_new_lines` is `true`, newline characters are preserved (`\n` and `\r`, hex `0xA` and `0xD`). Unicode-safe in JavaScript.
+**toBoolean(input [, strict])**        | convert the input string to a boolean. Everything except for `'0'`, `'false'` and `''` returns `true`. In strict mode only `'1'` and `'true'` return `true`.
+**toDate(input)**                      | convert the input string to a date, or `null` if the input is not a date.
+**toFloat(input)**                     | convert the input string to a float, or `NaN` if the input is not a float.
+**toInt(input [, radix])**             | convert the input string to an integer, or `NaN` if the input is not an integer.
+**trim(input [, chars])**              | trim characters (whitespace by default) from both sides of the input.
+**whitelist(input, chars)**            | remove characters that do not appear in the whitelist. The characters are used in a RegExp and so you will need to escape some chars, e.g. `whitelist(input, '\\[\\]')`.
+**isSlug**                             | Check if the string is of type slug. `Options` allow a single hyphen between string. e.g. [`cn-cn`, `cn-c-c`]

+### XSS Sanitization
+
+XSS sanitization was removed from the library in [2d5d6999](https://github.com/chriso/validator.js/commit/2d5d6999541add350fb396ef02dc42ca3215049e).
+
+For an alternative, have a look at Yahoo's [xss-filters library](https://github.com/yahoo/xss-filters) or at [DOMPurify](https://github.com/cure53/DOMPurify).
+
+## Contributing
+
+In general, we follow the "fork-and-pull" Git workflow.
+
+1. Fork the repo on GitHub
+2. Clone the project to your own machine
+3. Work on your fork
+    1. Make your changes and additions
+        - Most of your changes should be focused on `src/` and `test/` folders and/or `README.md`.
+        - Files such as `validator.js`, `validator.min.js` and files in `lib/` folder are autogenerated when running tests (`npm test`) and need not to be changed **manually**.
+    2. Change or add tests if needed
+    3. Run tests and make sure they pass
+    4. Add changes to README.md if needed
+4. Commit changes to your own branch
+5. **Make sure** you merge the latest from "upstream" and resolve conflicts if there is any
+6. Repeat step 3(3) above
+7. Push your work back up to your fork
+8. Submit a Pull request so that we can review your changes
+
+## Tests
+
+Tests are using mocha, to run the tests use:
+
+```sh
+$ npm test
+```
